What our research says

Stable Audio

A good choice for producers who care where the training data came from and want to keep their output, with a plugin that fits into a DAW. It gives you more control than a one-click song button but less singing-and-lyrics polish than vocal-focused generators.

Pros

Models trained on fully licensed data
Open weights for three of the 3.0 models, with output ownership under the Community License
No cap on how many generated files you can download
Web app, DAW plugin and API from one vendor

Cons

Credit allowances run out quickly on the lowest tier
The official pricing page does not render without JavaScript, so tiers are hard to verify
Organizations over $1M revenue must move to an Enterprise license

Udio

Udio still has the best arrangement tools of the prompt-to-song generators, with extend, inpaint and remix controls that let you shape a track rather than reroll it. Since the Universal settlement, though, what you make stays on Udio: no downloads and personal use only, which turns it from a production tool into a listening and sharing app until the licensed 2026 service and its terms arrive.

Pros

Section-level control: extend, precede, inpaint, variation and remix rather than generate-and-pray
Settled with Universal and licensed with Warner, which lowers the legal risk of the output itself
Free tier with daily credits lets you evaluate before paying
Mobile apps alongside the web app, per the terms' app clauses

Cons

Output cannot be downloaded and is limited to personal, non-commercial use under the current terms
Pricing is invisible without JavaScript, so plan limits must be checked inside the app
The licensed platform promised for 2026 had no public terms or launch details on the site today
No API, and no stated country or address beyond the corporate name in the terms
